JOHN E. HoLLowAY AND HAROLD E. BURWELL, or M noan, ooimncncum COMBINEDBRUSH. AND SUPPLY-HOLDER.

To all whom it may concern:

Be it known that we, JOHN E. HOLLOWAY and HAROLD E. BURWELL, citizens ofthe United States, residing at Milford, county of New Haven, State ofConnecticut, have invented an Improvement in Combined Brushes andSupply-Holders, of which the following is a specification.

This invention relates to combined brushes and supply holders forcontaining material intended for use in connection withsaid brushes, andespecially, although not exclusively, to combined tooth brushes anddentifrice containers, certain features of the invention howeverrelating to the supply holder or container per 86, independently of itsconnection with the brush.

The invention has for an object to provide a combined toothbrush anddentifrice container or the like of compact form which will keep thebrush and dentifrice in clean and sanitary condition, and which isconveniently arranged for use in connection 'with the standard packagesin which dentifrice is usually marketed.

Another obj ectof the invention is to provide an improved holder forcontainers, and particularly for collapsible tubes of the type generallyemployed to hold tooth paste and similar material, said holder havingmeans for conveniently ejecting a determined quantity of the contents ofthe tube, said ejecting means 0 crating to collapse the tube and belngof suc 1 a nature as to be easily operated and to permit the tube to becompletely collapsed so as to discharge all of its contents.

With the foregoing and other objects in view we have devised theimproved combined brush and supply holder which we will now describe,reference being had to the accompanying drawings, in which: K

Figure 1 is a side elevation of the device, showing the contents of thecontainer being discharged'upon the brush. 7

Fig. 2 is a side elevation showing the brush head. attached to thecombined holder and handle in position-for use.

Fig. 3 is alongitudinal, section showing the means for inclosing andprotecting the brush when not in use.

Fig. 4: is a detail viewshowing severalof the parts of the devicedisconnected from one another. 1

Serial No. 454,716.

Fig. 5 is a detail. view showing a col-,

discharge nipple of the device.

Fig. 6 is a detail view of the means for collapsing the tube and therebyejecting or discharging its contents.

Fig. is a section on the line 7-7, Fig. 6.

15 denotes a brush head having bristles 16 and a short shank 17 formedwith an enlarged end 18 provided with a threaded openlng or socket 19.20 denotes a holder for material to be used in connection with thebrush, said holder in accordance with one feature of the invention, andas herein shown, comprising a casing for inclosing a container in theform of a collapsible tube 21 having the usual exteriorly threadedoutlet mpple 22. 23 denotes a nipple provided at its inner end with anannular flange 24, said nipple being interiorly threaded at its innerend for attachment to the. threaded outlet nipple 22 of the tube 21 andhaving an exteriorly threaded outer end 29. to engage the threadedopening 19 in the brush head. 25 denotes a thimble having a threaded end26 (see Fig. 4) to engage exterior threads 27 on the open forward end ofthe holder 20, said thimble having an opening 28 through which theforward end 29 of the nipple 23 projects and a shoulder 30 to engage theflange 24 on said nipple and clamp the same against the end of theholder 20. The thimble 25- is preferably provided with a knurled annularrib or head 31 whereby said thimble may be readily unscrewed from thecasing 20 to permit withdrawal of the tube 21 and nipple 23 and theconnection and disconnection of said last named parts. 32 denotes a ed,when said cap is forced over said thimble, to expand the yielding openend of the latter and snap into the corrugation 33. The cap 32 may, ifdesired, be provided w1th a ring or loop 40, by which the device may besuspended when not in use.

The holder 20 is provided with a longitudinal slot 35 in which is guidedthe stem 36 of an operating knob or finger piece 37 located at theexterior of said holder, the inner end of said stem 36 being in threadedengagement with a substantially ovoid tube collapsing me er 38. Saidcollapsing member, while rou ded to avoid injury to the tube, is ineffect wedge-shaped with the thicker portion disposed toward the rearend of the holder 20 and of less diameter than said holder. 39 denotes aleaf spring having an opening to receive the stem 36 and interposedbetween the finger piece 37 and the exterior surface of the holder 20,said spring normally holding said finger piece elevated and thecollapsing member 38 in engagement with the top of said holder, as shownin full lines in Fig. 6. The stem 36 engages the collapsing member 38 ata slight inclinationto the axis of the latter and at a point slightlyforward of the center thereof, so that by depressing the finger piece 37against the tension of the spring 39 the forward end of said member 38may be depressed substantially into engagement with the bottom of theholder 20, as shown in dotted lines in Fig. 6.

In order to insert a tube of tooth paste, the thimble 25 is unscrewed,and the nipple 23 removed and attached to the outlet nipple 22 of'saidtube, as shown in Fig. 5. The tube 21 is then inserted into the holder20 through the open forward end of the latter, and the thimble 25replaced, thereby retaining said tube in said holder and clamping theflange 24; of the nipple 23 to the end of said holder, as aboveexplained. The brush head is normally attached to the threaded forwardend 29 of the nipple 23, as shown in Figs. 2 and 3, and consequentlyconstitutes a closure for the tube 21, the holder 20 in turn,constituting the handle of the brush. When the brush is to be used, thebrush head is detached and reversed, and the finger piece 37 pushedforwardly, thereby causing the collapsing member 38 to press upon therear end of the tube 21 and squeeze out the desired quantity of pastethrough the nipple 23 and upon the brush, as shown in Fig. 1. Thereafterthe brush head is replaced and the brush used in the usual manner, afterwhich the cap 32 may be applied to inclose and protect the brush untilit is to be used again. As the contents of the tube 21 are used thefinger piece 37 is pushed farther and farther forward, the collapsingmember 38 exerting a wedging action upon said tube and collapsing thesame progressively from its rear end forwardly. This operation is aneasy one which can readily be controlled to regulate the amount of pastedischarged with considerable nicety. In order to insure the completecollapse of the tube and the complete discharge of all of its contents,the member 38 may be pressed downwardly into the position shown indotted lines in Fig. 6 to exert any desired degree of pressure upon thetube, being at the same time moved forwardly, and thereby completelyflattening said tube against the Wall of the container 20.
